“The conference has been widely hailed as a success, and this is due in no small part to all those working at One Great George Street. It was a pleasure to work with you and your colleagues, and I would not hesitate to recommend OGGS as a superlative venue.

In addition, staff at reception and cloakroom were helpful, knowledgeable and patient, by turns; and the high standard of cleanliness was also appreciated.

The faultless support of OGGS staff, set in such beautiful surroundings, provided a fantastic backdrop to our most successful conference to date. A very memorable day! Please pass on my thanks to your colleagues, and I hope that we will hold another event with you again.”

“We were a little bit concerned when Highways Authority and Utilities Committee decided through their management company AlderCross to hold the national conference and exhibition at One Great George Street. We thought it would cause us major logistical problems being in Westminster. There was no need to worry, the assistance we received by the team was excellent. They were all very friendly, professional, and extremely helpful, they made everything so easy, no fuss, no drama, they just helped us in every way. What could have been very stressful turned out to be by far the easiest setup and breakdown of a conference. The Venue is a remarkable and beautiful building, the food served and their onsite cafe bar was perfect.”

“My most sincere thanks to you and all the team at One Great George Street for a really excellent event. Every aspect of the service provided by you all was of the highest professional standard while the food was absolutely superb. The performers were grateful to your technical team for their expertise. Thanks to the willing porters who helped transport all the equipment to and from the parking bay! or my part, I want to thank you personally for helping me throughout the long journey of putting the event together. The final result was, as many guests have told me, “a spectacular success that we'll never forget.””
